Message-ID: <4c348ac20703072215x63a7a315kd018e433c7a197d2@mail.gmail.com> Date: Thu, 8 Mar 2007 11:45:58 +0530 From: "Kanhu Rauta" <choiskanhu@...il.com> To: netfilter-devel@...ts.netfilter.org, linux-net@...r.kernel.org, kernelnewbies@...linux.org, linux-kernel@...r.kernel.org Subject: IP Defragmentation Hi list, I am using kernel 2.6.20.1. I have written a module,which will register a function at local_in hook, i have found a strange behavior with the packets getting in my callback function i.e [let say i am sending 1500 bytes to this machine from the network] ping -s 1500 <ip> 1>in case of fragmention i am getting only one packet at the hook,While analyzing the ip header it says this is the assembled packet(skb->len=1528,offset=0,MF=0). While dumping the data(for 0 to 1528 print skb->data[i]) it shows that only 1472 bytes are valid data and rest 28 bytes are something garbage. I verified this with ethereal. 2>I have dumped these packets in ip_local_deliver function after ip_defrag and before NF_HOOK,But the result is same. Can Anybody let me know why i am not getting the complete data ?
